Acanthopterygii (meaning "spiny-finned one") is a superorder of bony fishes in the class Actinopterygii. Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.
The suborder includes the berycids and their allies, but by far the largest member of the group is the Percomorpha, the most diverse vertebrate clade.
